Most 2015 Civics use a continuously variable transmission (CVT) automatic, while the sport-oriented Civic Si uses a six-speed manual transmission. The exact setup depends on trim and market.
Transmission options by trim
The 2015 Civic lineup centers on two main configurations. A CVT automatic is standard or widely available on most non-Si trims to maximize fuel efficiency, smooth operation, and everyday usability. The Civic Si is the performance-focused variant and uses a traditional 6-speed manual transmission for driving engagement.
- CVT automatic on most LX, EX, and EX-L trims (and other non-Si variants) – designed for smooth operation and improved fuel economy.
- 6-speed manual transmission on the Civic Si – a sport-oriented gearbox with a clutch pedal and traditional H-pattern.
Always verify the specific vehicle's transmission with its window sticker or owner's manual, as regional offerings can vary.
Identifying the transmission in your 2015 Civic
There are a few quick ways to tell which transmission your car has: observe the pedal setup (two pedals for automatic/CVT vs three pedals for manual), inspect the gear shifter (an automatic CVT shifter typically moves in a straight line with P-R-N-D, while a manual shifter has an H-pattern), and check the vehicle’s VIN or the original window sticker for the transmission code.
Why this matters for buyers and owners
Choosing the right transmission affects fuel economy, maintenance expectations, and driving feel. If you value sportier shifting and engagement, you’ll likely want the Si’s manual. If you prioritize ease of use and efficiency, the CVT-equipped trims are generally more convenient for daily commuting.
Summary
The 2015 Honda Civic mainly used a CVT automatic across most trims, with the Civic Si offering a traditional 6-speed manual. This setup reflects Honda's balance between efficiency and driving enjoyment in the ninth-generation Civic.
